From Our Advocates

In our experience with cystinuria cases, external reviews often succeed when the appeal includes peer-reviewed studies showing tiopronin's effectiveness for stone prevention, especially when conservative measures have clearly failed. The key is demonstrating that continued stone formation poses genuine health risks that outweigh the medication's costs.
